Tonsillotomy for Periodic Fever Syndrome: A Randomized and Controlled Trial

Area of Science:

• Pediatric Otolaryngology
• Pediatric Immunology
• Clinical Trial Research

Background:

• Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is a common autoinflammatory disorder in children.
• Tonsillectomy is an established treatment, but tonsillotomy presents a less invasive option with a potentially better safety profile.
• The comparative efficacy of tonsillotomy versus observation for PFAPA syndrome requires further investigation.

Purpose of the Study:

• To evaluate the efficacy of tonsillotomy compared to observation alone in children diagnosed with PFAPA syndrome.
• To assess symptom resolution and fever burden at a 3-month follow-up period.
• To determine the need for subsequent tonsillectomy in both treatment arms.

Main Methods:

• A randomized, multicenter trial with a sequential design was conducted.
• 16 pediatric patients with PFAPA syndrome were randomized into either a tonsillotomy group or an observation-only control group.
• Daily symptom diaries were utilized to monitor disease activity and treatment outcomes.

Main Results:

• A significantly higher proportion of patients in the tonsillotomy group (87.5%) achieved symptom resolution compared to the observation group (25%) (p=0.0021).
• The mean number of fever days compatible with PFAPA syndrome was substantially lower in the tonsillotomy group (0.8 days) versus the control group (6.5 days) (p=0.007).
• All patients in the observation group ultimately required rescue tonsillectomy, while none in the tonsillotomy group did.

Conclusions:

• Tonsillotomy appears to be an effective treatment for children suffering from PFAPA syndrome.
• The procedure demonstrated a significant reduction in PFAPA symptoms and fever episodes.
• Further research is warranted to establish the long-term effectiveness of tonsillotomy in managing PFAPA syndrome.
